17 clai s.

The present invention relates to wire stitching machines for stitching cardboard cartons or boxes and is more particularly concerned with the. type of machine used for progressively stitchg'ing corrugated cardboard cartons.

In the manufacture of cartons of the larger dimensions for transit purposes, use has been made more recently of ioldable boxes produced from corrugated cardboard. Such cartons, when m collapsed, occupy a comparatively small space.

The stitching of these cartons was hitherto confined to the use of flat wire stitching machines. The carton was collapsed as required and placed on a horizontal arm of the machine, said arm containing the tools for clinching over the staple legs, and after completion of the stitching, had to be withdrawn again. In order to obviate the manual removal of each completed carton from beneath the stitcher head the so-called progresgo sive stitching has been resorted to, according to which the collapsed cardboard carton to be stitched is so placed on a feed table, provided on the machine, that one of the overlapping closing ends of the box is positioned just above and the other below the dividing portion of a suitably shaped tongue, arranged above the feed table. Subsequently, during the progress of the 'carton to the stitcher head, both ends are brought together and then pass over the clincher member. Consequently, it is possible, in progressively stitching the cartons, to cause the latter to pass along the feed table to the stitcher head. and when stitched, to continue through and to be ejected at the further side of the feed table. In

dealing with corrugated cardboard cartons in a Wire stitching machine it is sometimes desirable to position the staples obliquely to the corrugations in order that the legs of such staples,'when clinched over may lie in two difierent corrugation 4.9 tracks of the cardboard.

The object of this invention is to provide a wire-stitching machine whereby stitches may be progressively inserted with particular advantage in corrugated cardboard boxes or cartons at any 4.5 desired angle to the corrugation tracks of the work by a mere variation of the direction of its travel through the machine.

. To this end according to the invention, the machine which, as shown by way of example,

may be of the treadle controlled type and having a stitcher head in a permanently set position, is provided with mechanism enabling by simple adjustment the direction of travel of the work to be readily varied whereby say a collapsed corrugated cardboard carton may be caused to Germany April 25, 1930 be guided beneath the stitcher head with its corrugation tracks parallel to or at any predetermined angle to the position of the stitches to be applied thereto.

The above and other features of the invention will be more readily understood by reference to the accompanying drawings which illustrate one embodiment thereof in a suitable stitching machine, in which:

Fig. 1 shows the stitching machine in side elevation.

Fig. 2 is a front elevation thereof.

Figs. 3 and 4. show the stitcher tongue and box guides set in the straight and oblique stitching positions respectively.

Fig. 5 is a detail view showing the means for attaching the stitcher tongue to the supporting bracket.

Fig. 6 is a side elevational view of the adjustable treadle, and

Fig. '7 a plan view thereof.

Referring to Figs. 1 and 2, the main frame 10 of the wire-stitching machine supports a wirestitcher head 11 of known type which in this embodiment is power driven and controlled in the usual manner by a tripping clutch operated through the linkage 12, from the treadle 13. A box support 14 of known design extends horizontally from the main frame 10 to beneath the stitcher head 11. A feed table 15 is detachably fitted upon the member 14 and sheet or box guides 16 adjustably mounted thereon. A stitcher tongue 17 supported at one end thereof from the mainframe 10, to one side of the stitcher head, as shown in Fig. 2, extends transversely of the feed table between the guides 16 and terminates beneath'the stitcher head 11. The supported end of the tongue 17 is provided with an upwardly extending flange 18 which is secured by readily releasable means to a supporting bracket '19. The flange 18 is attached to the tongue 17 so as to form aledge 17a which is clearly spaced from the surface of the tongue (Fig. 1). The extremity of the member 18 is flared out to form a mouth 18a (Fig. 2).

Referring more particularly to Figs. 3, 4 and 5, the bracket 19 is formed by a centre hub 20, attached to the main frame by means of a downwardly extending arm 21. The hub 20 carries two arms 20a and 2% which, preferably are of circular cross section and have their outer extremities drilled and threaded to receive a looking screw 22a. The arm 20a is set parallel to the support 14. whilst the arm 20b is set obliquely thereto in the same horizontal plane. The flange 18 attached to the tongue 17 is formed integral with a collar 22 which slidably fits upon either arm 20a, 20b, and. is held thereon by means of the locking screw 22a. The clincher mechanism 23 is set within a circular casing which is rotatably mounted upon the free end of the tongue 17 directly beneath the stitcher head. The guides 16 are provided with slotted lugs by which they are adjustably bolted to the feed table. Instead of effecting the setting of the tongue '17 by fitting it on to the requisite arm 20a or 2011 its pivot could be arranged on a separate bearing (not shown) adapted to be screwed to the frame at requisite points.

The control treadle 13 (Figs. 6 and 7) is secured to side shanks 24 which are adjustably held in clamping members 25. The latter are pivotally mounted at the base of the machine frame and the shanks 24 are held therein by means of set screws 25a.

The operation of the stitch positioning mechanism is as follows:

If the machine is to be used for progressively positioning staples parallel to the line of corrugation of the collapsed cardboard carton, the mechanism is positioned as shown in Figs. 1, 2 and 3. That is to say, the stitcher tongue 17 is mounted upon the arm 20a and held thereon by means of the screw 22a. The guides 16 are set parallel to the longitudinal axial line of the tongue 1'7 which, mounted as above described,is rotatable about the axis of its supporting arm 20a. The collapsed cardboard carton is then placed on the feed table to the left-hand side of the stitcher head (Figs. 2 and 3) so that the lower of the two overlapping edges to be stitched is positioned on the tongue 17 and the upper edge 17a. Upon being progressed toward the stitcher head in the direction of travel indicated by the arrow A, the edges move clear of the ledge 17a and come together to lie upon the clincher mechanism beneath the stitcher head, and so receive a stitch or stitches parallel to the line of corrugation.

It will now be clearly seen that in order to position staples in, for instance, a corrugated.

cardboard carton, at an angle to the corrugations the necessary adjustments are very readily made.

The winged headed screw 22a is removed and the tongue 17 removed from the arm 20a, and mounted upon the arm 20b being locked thereon by means of the screw 22a. The tongue 17 is now positioned at an oblique angle to the stitcher head (Fig. 4). The guides 16 are swung round to lie parallel to the adjusted longitudinal axial line of the tongue, and the clincher mechanism readjusted above its vertical axis to register correctly with the stitcher head stapling mechanism. Since, by the adjustment above described, the feed end of the tongue now stands further forward from the machine, the operator may have to change position accordingly. If this is necessary the control treadle 13 is conveniently brought within reach of this altered position by slackening the set screw 25a and adjusting the shanks 24 as required. The collapsed cardboard carton, positioned on the feed table and tongue 1'7 as above described, is now progressed toward the stitcher head in the direction of travel indicated by the arrow B i. e., at an angle to the horizontal position of the stitches or staples to be inserted therein.

If the cardboard is corrugated, each leg of the staple is thus clinched over to lie in a separate corrugation track, whilst the head of the staple is positioned obliquely to the line of corrugation.

In order to utilize this machine for the more usual type of cardboard box stitching, the stitcher tongue and feed table may be readily removed and the box support 14 fitted with the clincher mechanism in the known manner.
